WiFi Schields

WiFi is the most popular interface of IoT endpoint devices. WiFi connectivity for microcontrollers is frequently implemented using WiFi chipsets that connect via SPI or UART to the microcontroller. The CMSIS-Driver framework defines both the WiFi interface itself and the related drivers for UART or SPI.

The Arm:CMSIS-Driver pack contains MCU independent driver implementations for various peripherals including several popular WiFi chipsets as listed below. The pack is developed on GitHub.
